Niki Laudas chief mechanic from March used to drink in a pub I worked at and told loads of stories about him.

Often the mechanics would walk into the garage on the morning of a race and Lauda would be found covered in oli and grease after stripping apart the engine as he was fixing the car himself.

He knew his way around a race car.

A lot of stories like this about - I was just reading about how when one of his airline’s planes crashed, he proved to Boeing that it was their fault and then forced them to admit it publicly. Really knew his stuff.
